Pac-Man Restoration March 26, 2010
The monitor was already out for the previous photos on
Here's how that's done. The monitor in this machine was a Wells Gardner, but it
had terrible screen burn-in and other issues like a red appearance and torn right
side. That's just too much to deal with, so I chose to change it out with a better
one that I had laying around.
SAFETY NOTE: Monitors that have been in service pose a dangerous shock hazard. The
high voltage present at the flyback anode on the side of the CRT must be drained
to ground. You can find video tutorials on
that detail this procedure.
After the CRT is safely discharged, disconnect all the wires and remove the four
corner bolts. Grip the monitor by the cross brackets (red circle below) and slide
it out the back.
Here's a look at the CRT screen burn-in--a dreaded but inevitable issue on a Pac-Man
because of the fixed text and maze locations. With all the other issues
this one had, it was time to retire it.
Simply reverse the procedure to install the replacement monitor. This one was
used, but had light burn-in and had just been re-capped (new capacitors installed).
A quick hook-up and test determined that all was well. The machine is still in
the Ms. Pac-Man configuration, but the colors are bright and sharp. A BIG improvement.
The tattered, rusty control panel needs attention and the game is nearly unplayable with that
microswitch replacement joystick. Fortunately, I happen to have a number of
original Happ leaf-switch joysticks. :)
Strip down the control panel all the way to the metal. I use a really good, sharp
gasket scraper left over from my days as an auto mechanic. A few taps on the handle
with the hammer helps loosen the really stuck places around the carriage bolts
If you find the going too tough this way, you can use a heat gun to soften the
overlay. It should then scape off relatively easily.
